Prototyping with Phoenix LiveView: A Perfect Play Queue III
This time we went deep into JS / LiveView interop, implemented track position scrubbing, and added intelligent play queue auto-scroll behavior, that shows the currently playing track on the top of the queue, if user doesn’t scroll to a different place manually.
Preparing to Refactor with Better Unit Tests
TL/DR: The last time we looked at this code, we wrote property tests. The property tests used generators to create input, but the actually testing of the invariants was just regular Elixir code. In this post, we’ll look at rewriting those property tests as standard ExUnit tests, giving us better unit tests.

7th video in the series about building cryptocurrency trading bot in Elixir
7th video in the series about building cryptocurrency trading bot in Elixir - this time we will build a BinanceMock application
We will create a new application called BinanceMock. It will have the same functionality as the Binance module so we will be able to use them interchangeably. In the future episode(s) the BinanceMock will become a foundation to allow us to perform backtesting. Besides creating the application itself, we will also modify the leader and the trader to reference the config to figure out which client to use instead of the previously hardcoded Binance module.
Designing For Elixir Compiler Hints
There are some nice new features coming in Elixir 1.11, and one many folks are excited about are some new compile-time checks. The one I’ve heard the most excitment about is the the compile-time check for non-existent fields in structs. But, I’ve got some concerns about how folks might use this and how it might change application design.
